High variation on results (induced voltage on a coil) - 3D Transient Flux

Recommended Posts

Hello.

I've been struggling with the simulation of a sensor consisting of a coil with a ferromagnetic core and a magnet. The main output to analyse is the voltage induced on the coil by a rotating target. I'm modeling the coil as stranded-coil conductor coupled with a series resistor (see attached circuit.png). When measuring the voltage across the coil, I'm looking at very high fluctuations in voltage (see attached results.png), if I take the derivative of the flux (flux.png) through the coil, the behavior is minimized a bit, but still present. 

Any ideas to improve this high variation?

 

Thanks.

Hi,

Can you send me you Flux project (zip format without results).

 

Best regards.

Hi,

Thanks for your response. This is a company project, unfortunately I'm not able to share any confidential information unless you are an Altair member. If that is your case, could you please share your email?
